Fluorites formed in uranium mineralization period in the Zoujiashan and Shazhou uranium deposits have ε〓 values from -6.7 to -8.3 and I〓 values from 0.7145 to 0.7204, similar to their host rocks (porphyroblastic lava and sub-granodioritic porphyry) which have ε〓 values from -6.2 to -9.4 and I〓 values from 0.7121～0.7192. On diagram of ε〓- t, the fluorites and host rocks plot in similar area within the evolution field of the basement rocks at Xiangshan. The lead isotopic compositions of pyrites formed in uranium mineralization period plot as a line on diagram of 〓Pb/〓Pb vs.〓Pb/〓Pb. The host rocks plot at the lower value end. Calculation based on the slope of the line and the mineralzation age yields age of 144Ma for the geological body which provided uranium for the mineralization.

邹家山和沙洲铀矿床成矿期萤石的ε〓值(-6.7～-8.3)和I〓值(0.7145～0.7204)与赋矿围岩(碎斑熔岩及次花岗闪长斑岩)的ε〓值(-6.2～-9.4)和I〓值(0.7121～0.7192)相似，在ε〓-t图上，成矿期萤石数据点的投影范围与赋矿围岩的基本吻合，且均落在相山元古宙基底演化域范围内；成矿期黄铁矿的铅同位素组成在〓Pb/〓Pb-〓Pb/〓Pb关系图上呈线性分布，而火山岩的铅同位素组成位于此相关线的低值一端；利用异常铅线的斜率及成矿年龄计算出富铀地质体的形成年龄为144Ma，这与赋矿围岩的成岩年龄(135～140Ma)非常接近。

The time of the pedogenic process was in the last ice age, therefore this area was colder and drier in climate and lower in sea level than today. The main chemical process in the soil was oxidation, a period of the formation of oxide minerals such as limonite. With the deposition and covering of the marine facies layer in the postglacial period, the soil turned into diagenetic process. Consequently the chemical process in the soil was dominated by reduction and this process was the main development period for nodules of iron-manganese carbonate to form.

成土期处于末次冰期低海面、气候寒冷干燥期，土壤的化学过程是以氧化作用为主，是褐铁矿等氧化性矿物形成时期；冰后期海相层的沉积覆盖使土壤层进入成者阶段，土壤层的化学过程以还原作用为主，成岩过程是铁锰碳酸盆结核的主要生成期。

Among 391 ever and current smokers, 59.6% were in precontemplation, 17.9% were in contemplation, 10.2% were in preparation, 7.4% were in action, 4.9% were in maintenance stages.

Result: Compared to normal subjects, some functional regions associated with encoding, maintenance and retrieval process showed increased activation in schizophrenia patients, i.e. right precuneus for encoding process, left PMA, left DLPFC, right precuneus and left VLPFC for maintaince process, left PMA for retrieval process. In addition, subcortical structures, primary motor cortex and some verbal regions in left temporal lobe also showed more activation.

GA3 contents, POD activities and invertase activities started to increase significantly while IAA contents started to decrease significantly when plants entered the critical stage of flower-bud differentiation; GA3 contents, POD activities and invertase activities emerged high apex value while IAA contents emerged low apex value when plants entered stage of primar...

当植株进入花芽分化临界期时，叶片中GA3含量以及POD和转化酶活性均开始剧增，而IAA含量开始剧减；当植株进入第1侧花茎原基分化期和第2～3侧花茎原基分化期，叶片中GA3含量和POD、转化酶活性均出现一高峰值，而IAA含量出现一低峰值。可见，青花菜侧花茎每一级的花芽分化要求较高含量的GA3、较低含量的IAA和较高活性的POD、转化酶。

We have concluded five key tectonics geologic characteristics of Chinese foreland basins based on the study of the sedimentary infill, tectonics evolution, tectonic dynamics, spatial location distribution and structural deformation geometry.(1) The foreland basin is the superimposition of the compression sedimentary stratigraphic sequence with the extension basin, and the foreland basin includes underlying rift basin and upper dustpan flexure deposited basin.(2) The foreland thrustfold structural deformation has occurred four times since the Protozoic, in the Late Caledonian, Late Hercynian, Indosinan and Late Himalayan, respectively.(3) The foreland basin developed based on the control of two factors that are the basin basement collaged by many small plates or terrains and the rejuvenation of ancient orogenic belt, so the foreland basins or foreland thrusts are located in front of ancient orogenic belt.(4) The foreland basins and the rejuvenation of ancient orogenic belt make up a giant basinmountains system resulting from the distant effect of IndiaEurasia collision, which is located on the outer circle of Tibet Plateau, so the thrust deformation intensity, basin deposition range and coupling between orogenic belt and basin changed from strong to weak as from interior to outer circle of Tibet Plateau.(5) There are many structural styles of the thrust and fold belt in different basins, such as brittle behavior faultrelated fold, ductile behavior basementinvolved structure, basementinvolved faultrelated fold, and salt structure.

在综述前人认识的基础上，笔者通过对中国前陆盆地的构造演化历程、沉积充填特征、构造成因及其空间分布规律、构造变形特征等的研究，提出了中国前陆盆地构造地质发育的5个主要特征：(1)两种不同性质的原型盆地发生正反转的叠合性，即挤压构造下作为&本体&的前陆层序与拉张构造下作为&基础&的裂谷、断陷盆地之间的叠置；(2)显生宙以来中国大陆先后发生了4期前陆冲断构造演化的多期性，它们分别是加里东晚期、海西晚期、印支期和喜马拉雅晚期；(3)基于小克拉通基底拼贴后在造山带前缘复活再生的继承性，即统一拼合大陆内部的构造变形导致古造山带的复活，在古造山带边缘发育新生代前陆盆地或前陆冲断带；(4)在空间分布上受环青藏高原巨型盆山体系控制发生陆内变形的系统性，在环青藏高原巨型盆山体系内构造变形强度、盆地沉降幅度、盆山耦合程度等从内环向外环依次降低，从古造山带向克拉通方向构造变形强度依次降低，构造变形样式逐渐简单、构造变形时间依次变新；(5)前陆冲断带的构造样式由于受边界力学条件和沉积地层介质作用而具有多变性，存在沉积盖层内脆性变形的断层相关褶皱、造山带前缘韧性变形的基底卷入构造、与走滑构造相伴生的基底卷入的断层相关褶皱、盆地内部塑性变形的盐构造。
